Running mknod to create /dev/sr0 on the first computer doesn’t help. The drive works fine on my second computer, and it used to work on my first computer. I think the last time it worked on my first computer was when I was still running initscripts. I’m using systemd and the 3.0.65 kernel on both computers.

Can you post the output of the following:

pacman -Qi linux linux-lts
uname -a

I looked at the output from those commands, and realized that I had installed linux-lts 3.0.65 on both computers, but hadn’t rebooted one of them, so it was still running 3.0.64. I rebooted that computer and everything works now. Oops.....
